[vcf-midatlantic] Non-IBM CD drive on PS/2

Any PS/2 experts on the list? I have a question about getting non-IBM stuff working on a PS/2 Model 80 running PC-DOS 4.01. Has anyone gotten a non-branded SCSI CD-ROM Drive working with a SCSI-based PS/2?
I’m using the PCem emulator which, if you don’t know it, is an emulator like DOSBox but emulates specific PC-compatible brands and machines. So, I can do a Compaq DeskPro/386 or an IBM PS/2 and it emulates all the quirks. It’s pretty neat. I had both of those machines when I was in college so it’s a great step back.
Anyway, I’ve learned about ADF’s and stuff, so I have a pretty good working system at this point — a PS/2 Model 80 with an IBM SCSI storage controller (it’s the “SCSI controller with cache” model), 312mb drive, and a SoundBlaster card. The only thing that doesn’t work is the emulated CD-ROM.
PCem emulates a generic SCSI CD that I have assigned to SCSI ID 6 and I’ve run the Reference Disk. I’ve read that if it’s not an IBM-branded CD, there are issues with getting it working. I’ve loaded the ASPI4B SCSI driver and the IBMCDROM driver (with the “/i “ and “p:2” params, but it barfs on loading.
If anyone can give me a push, that’s be great. I can add a CD definition to the source code, but I’d need info from a real IBM CD drive like the ID string, serial number, etc.
